Function Fit

I'd really appreciate a math type having a look at the following data series and letting me know if it's possible to fit them to a quadratic.

Knowing it's possible would be cool. Actually generating the quadratic would be extremely useful and much appreciated.

135 180
225 360
310 545
385 725
455 900
520 1000
605 1270
670 1450
740 1635
810 1815
890 2000
970 2180
1070 2360
1125 2500

Cheers

It would be a challange to find one equation that fits all of these values. However It is certainly possible to use a series of quadratic type equations to create a smooth line between these sets of points. This would enable us to work out the likely values at any point between the start and the end of the series although it would depend on the level of smoothing. If one was wanting to then project the line further in order to predict the next likely value this might be possible as long as it is not too far away from the last value.

There are no further 'values'. Just these ones.

It's the 'manufacturers' table for 'calculating' usable capacity from 'manual' 'dipping' operations for my oil 'tanks'. I just wanted 'a' function 'rather' 'than' a table lookup.

Sorry 'it' isn't 'more' exciting.

FindGraph seems to fit data to equations.

I had a brief go with it but it seemed to produce totally wrong equations. I hope you have more luck.
